We propose a novel artificial medium, which locally provides both the optical nonlinearity and simultaneously the phasematching for the macroscopic build-up of the generated field. This is achieved by a special assembly of semiconductor quantum wells, which by careful design are both nonlinear and appropriately dispersive. A critical point for a practical realization of this meta-material is it...

The numerical simulation of the dynamic interaction between hydrocarbon reservoirs and wells has been an object of study for over three decades. Such a coupled approach is necessary to solve a variety of dynamic flow problems, such as pressure transient analysis (well testing) with wellbore storage, liquid loading, near-well reservoir clean-up, unstable gas lift, or the development of smart wel...
